To all whom it may concern:

Be it known that I, WILLIAM D.. PInnsoN, a citizen ofthe United `States,residing at lfVaterbury, in the county of New Haven and State ofConnecticut, have invented certainnew and useful Improvements inSpooling Mechanisms, of which the following is a specification,reference being had therein to the accompanying drawings. l

This inventionrelates to a new and improved spooling mechanism of thetype generally used in `winding wire upon a spool or the like andassociated with a wire drawing machine. i

There-V are numerous other uses to which this mechanism can be appliedandl therefore do notlimit myself to the use above set forth. I j

`It is the object of this invention, among other things, to provide-amechanism of the character mentioned wherein fthev rotary spindle willreceive a reciproca-tory motion adjustable in length but Vuniform in thespeedof its travel, and both of these actions controlled by a make `andbreak connection with a source of power, of simple design, that isreadily controlled, and to accomplish these and other desirable resultswith mechanism of simple design, that is economically constructed, andreadily assem` bled, so as to withstand the maximum strain, with themlnlmum wear. To these, and other ends, my invention consists in thespooling mechanism, havingV certain details of construction andcombina-y tions of parts, as will be hereinafter described and more inthe claims. j

'Referring tothe drawings, in which like numerals of reference designatelike part-s in the several figures; j

Figurer 1 is 'a fragmentary front elevation ofmy improved .spoolingmachine, partly in section and I i j l Figure 2 is a fragmentarytransverse sectional view thereof, theparts in section being` takenvgenerally upon line 2-2 of Figure 1. j y

This typel of mechanism is usually associated with a wire drawingmachine for winding on a spool the wire drawn thereon.

With some machinesthe spool moves back and forth while rotating, duringwhichtime `the wire `is wound thereon between the particularly pointedout,`

flanges thereof andin other casesthe spool mayV merely rotate without areciprocatory movement in which lcasethe wire is guided thereon.

` In these operations'it is desirab-le that the spool or the guide,whichever it may be, should move back and forth at a uniform speed soyas to insure a uniform winding of the wire. Thisis accomplished in myinvention, with mechanism that will p-ermit of such adjustments as willvary the extent of the-K, reciprocatory movement without varying theuniform speed of travel thereof and with the exercise of the minimumlabon and skill. l v l Referring to the drawings; 10 designates the bodyof the machine, tothefunderside of which is fixed the companion brackets11 within which is slidably mounted the traverse bar 12 that is heldagainst lateral movement in one direction by the caps 13.

This body member may beof any convenient form or shape and mounted uponstandards or legs, or attached directely to a wire` drawing or similarmachine, or otherwise supported, within the, spirit ofmy inven-` tion. jf

Secured on the ytop yof the` body 10 are the standards 14 ,and 15,within the former of which the spindle 16 is rotatably mounted and inthe latter of which a sleeve 17` is journaled, being' held againstendwise movement in one direction by a collar 18 and by a shoulder 65.The spindle is slidable within the sleeve 17 and held againstv rotationtherein by the key 35 which projects into a spline or keyway in thespindle.,

On one end of the spindle 16 is a spool 19 which is Y connectedtherewith in any well known manner. The shape, formfand size of thisspool obviously can be varied, and it may be attached or secured tothespindle also in any well known or convenient man-A the sleeve and drivenby a beltfrom any source of ower. 4 the sleeve 1 but heldagainstfrotatio'n thereon by a sliding fit key 22is a cone pulley 21VThe sleevei'll is rotated through a cone pulley 20 which is rotatablymounted upon Slidably mounted upon` Sov Sio

. the looknuts 33 on thesleeve 17 shown inFigurefl, the handle 31' whichis integral blocksorthegroove into which they project are subjected toanything' butl the Aniostv v,spindlevand Stillperniit a slipping ofthe." spool during the winding ovperatio'n.

' it is almost impossible to time the'speed with link 28 is thrown totheright Yand the pulleys 20 and 21 and friction disk 32arev all underspring tension, thus rotating the u sleeve 17 and spindle 16.

"The rotation of "the1 spindle is stopped by moving the lever 31 tothexleft, that is,` to

the position lshown by ybroken lines in Fig-z ure 1, at which time thelhinged connection of the links 28 and 29 will bein a substantiallystraight line, also outlined 'by broken lines, with the link 28 engagingthe stop lugSG on the lever 25.` lVlienso positione'd the pulley 21 isAmoved to the right and the spring 34 is compressed7 thus `removing thefriction .upon the? disk and cone pulley' 2Q.' y y i, u

There is no 'pressure againstvthe; blocks 24 within the groove' 23except when the spindle 1S is at rest7 therefore, neither the nominalwear; Thus to put the spindle'gin' motion it is onlygnecessary. to*Yshift y,the liandle`31 froinjhe dotted .to kthe full line position,vwhich niovesthe pulley 21 against,l

YThis basarseally been doneby a' lloose belt drive; which v1s thinojs it slips atpthewrongitiine,andd'rnotf unsatisfactory because .'amOlg" other' sufficiently' `.at theright time..

The mechanism hereinsliown gea/red nie'chanisrn 1Vasfused,onwtheordinary" engine lathe for drivnig'the spindle.

for driving" this spindle V may be adaptedfor purposes" other than thisparticular typefof `machine Y and the spindle may also bedrijven byoth'e'rftypes mechanisifn:l.l for ill ulstration',y the l p m V jtutedfor the spool 19;Y

Journaled in thebody 1.0" and held"against,l endyvise yinovenienttherein `by anyv Voon- V` venient' forni ine'Chanisni", is 4'shaft 37jhaving,- av worin 38 thereon,which.Ineshesgv Vshaft40 journaled inabracket 41 securedto the' body 10 and having a heart shaped cani 42 uponthe opposite end thereof.

A cone pulley 43 keyed or' otherwise iXe'd on the shaft 37 is driven' byal belt 44 from the cone pulley 21 so` that the spindle 16- and shaft 37come to a full stop at one and the sanre time.

Rotatably'niounted upon the studs 45 fixed in thebar 12 are the canirollsy 46, both of which are always'in contact withthe Yface ofthe heartshaped earn 42. As both sidesof this cani are alike, any two pointsdiani'etrically' opposite each other are the saine distance apart asevery other' two points so related, and therefore' this cani iinparts a.positive uniform reciprocatory ino tion to the bar 1 2 in bothdirections and also an instantaneous kreverse movement at each endofeach stroke.

The link bar 47 providednear its opposite ends with'slots 48, within'theupper of u'fhich'is lSlidalbly mounted the bloc 49 and in the lowertheblock 5,0. The block 'threaded portion of the block 49provide forsuitable ,operative `connection therebetween andthe link bar;y l

The block 50 is lnountedruponastud 55 that projects through the bari12andhaving` a nut, 56v` uponthefouter end thereof'.

This link bar 47`is pivotally mounted at a point between the endsthereof upon la stud 57 having". a T-head 58 which is movably mountedwithin alslot59 inthe body' 10, wandf isprovided withsuitable collars610 and61, as is usual. n Y v vlThe axis ofthe shay ".40` is' normal tothe path ofmovement of the traverse bar 12',

which latter is parallel* with the Aspindle-16V so that `areciljnocatory movement of-thefbar 12y is iinparted tothe 'spindle 16'.The length of the reciprooatory nioven-ient of the spindle 1G Vis variedwithin' its/extreme limits by shifting' the position of the stud 57 thatlfornns a ,fulcrurn for the bar 47,-thus producing" in the spindle anabs'ohitel'y'vari-V uniforrnspeedofmovement. y l
